A Christmas sweater is one thing — or a Santa hat, if you're temporarily employed at a department store — but a man should not be dressing up in costume on a holiday. And it's enough that an entire city dyes a river green every March 17; must every post-college drinker dress head-to-toe in the color as well? We think not.

So, good news: This spring, adding a pop (we repeat: pop) of color to your wardrobe is very much the thing, and along with orange and pink, green is very much a color of the moment. You can get a sense of the season's emerald mood above — a few accessories, a little military inspiration, a lot of new shades ("parakeet green" is worth adding to your vocabulary) — but go ahead and get something for yourself in honor of this Thursday. Just don't wear it all at once. Then call your new St. Patrick's Day shirt thematic for a day, and let it last through summer, if not a lifetime. Slainte.
